This RESTful Actix Web API illustrates how to use a MySQL database as a data source for various endpoints.

You'll need to have a MySQL (or compatible) server running on your machine to test this example.

All the following commands assume that your current working directory is this directory. I.e.:

$ pwd
.../databases/mysql

1. Create database and tables:

   The sql directory contains the SQL files used for database setup:

   mysql -u root -p < sql/0_create_database.sql
   mysql -u root -p my_bank < sql/1_bank_details.sql
   mysql -u root -p my_bank < sql/2_branch_details.sql
   mysql -u root -p my_bank < sql/3_teller_details.sql
   mysql -u root -p my_bank < sql/4_customer_details.sql

   For each step you will be prompted for the root user's password. If there's no password set on the root use, just hit enter again.

2. Create a .env file in this this directory:

   SERVER_ADDR=127.0.0.1:8080
   MYSQL_USER=root
   MYSQL_PASSWORD=<password>
   MYSQL_HOST=127.0.0.1
   MYSQL_PORT=3306
   MYSQL_DBNAME=my_bank

   Update "MYSQL_USER" and "MYSQL_PASSWORD" values with the correct MySQL user/password.

3. Run the server:

   cargo run

4. Using a different terminal send requests to the running server. For example, using HTTPie:

   http POST :8080/bank bank_name="Bank ABC" country="Kenya"
   
   http :8080/bank
